Area of triangle = \( \frac{1}{2} \times \text{base} \times \text{height} \)<br><br>
&bull; RSTU is a rectangle with UV = VT (V is the midpoint of UT)<br>
&bull; The shaded triangle shares base RS and has height equal to the rectangle width<br>
&bull; From the figure, Area = \( \frac{1}{2} \times 9 \times 6 = 27 \) cm&sup2;<br><br>
Final Answer: 27
